MACHINE FOR MANUFACTURING GLASSWARE.

SPEGIFIGATION iorming part of Letters Patent N 0. 653,412, dated July 10, 1900. llpplication filed January 26, 1900. Serial No. 2,826. (No model.)

To all whom, it floaty concern.-

Be it known that LPHILLIP EBELING,3. citizen of the United States, residing at Findlay, in the county of Hancock and State of Ohio, have invented or discovered certain new and useful Improvements in Machines for the Manufacture of Glassware, of which improvements the following is a specification.

The invention described. herein relates, to certain improvements in machines for the manufacture of that class or kind of glassware having one part formed by pressing and another part by blowing; and the invention has for its object a construction of mechanism whereby the pressed portion of the article and a blank for the blown part may be sim ultaneously formedin a suitable sectional mold, one part or section of which is then removed and the blank portion then inclosed in a blowmold and expanded therein.

It is a further object ot' the invention to provide for the transferof the partially-formed article from the pressing to the blowing position and to provide for the simultaneous but independent pressing and blowing operations.

The invention is hereinafter more fully described and claimed. I

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of my improved machine. Fig. 2 is a sectional elevation through the pressing portion of the machine, the plunger and its operating mechanism being omitted. Fig. 3 is a similar view through the blowing portion of the machine. Fig. 4 is a perspective view of the lower table, showing a blow-mold in position thereon. Fig. 5 is a detail view showing the'means for locking the blow-mold; Fig. 6 is a sectional view illustrating the manner of forming the pressing portions of an article having the blown portion formed by blowing through the pressed portion; and Fig. 7 is a view similar to Fig. 3, showing the construction of mechanism for top blowing.

In the practice of my invention a supporting post or pillar 1 is secured on a bed-plate 2, which is preferably provided with wheels 3 to facilitate the moving of the machine from place to place. A portion of the post or pillar is threaded for the internally-threaded sleeve 4, which is provided with a flange 5 for supporting the rotatable table 6. A platform 7, having radial projections or brackets 8 9 10, is supported by posts 11, secured to the bed-plate 2. This platform serves as a support for the annular table 12, which is preferably mounted on friction-rollers, as shown in Figs. 2 and 3. While any suitable means may be employed for insuring the rotation of the tables 6 and 12 in unison, the construction in Figs. 2 and 4 is a convenient means for that, purpose. As shown, a series of threaded studs 13 are secured to the table 12 and extend up through the table 6. Nuts 14E and 15 are placed on these studs above and below the table 6 and serve to hold the tables in the desired vertical relation to each other. When it is desired to increase the distance between the tables, the upper nuts 14 and the jam-nut 4? are screwed up and the table 6 is rotated to the right, thereby rotating the sleeve 4, the friction between the table and sleeve being sufficient for that purpose, when the sleeve is free to turn. When the table has been raised to the desired height, the jamnut 45* is screwed to bear on the sleeve, the nuts 15 screwed up to bear on the under side of the table, and the nuts 14 turned down to clamp the table. In lowering the table the nuts 15 are turned, the table rotated to the left, thereby screwing the sleeve down until the table bears on the nuts 15, whereupon the nuts 14 and 4 are turned down to clamp the table in its new position.

' The table 6 is provided with a series of openings through which a boss or projection 16 on the press-mold 17 projects. These openings are made sufficiently larger than the boss or projection 16 to permit of the mold, which is of the usual sectional form, to be opened wide enough for the removal of the completed article through the radial slots extending from the openings through the periphery of the table, as hereinafter described. In order to center the press-mold above the openings, the table 6 is provided with annular centering-ribs 18 around. the openings, as shown.

in Figs. 2 and 3, and the under side of the mold 17 is recessed, so as to fit around said ribs when the mold is closed. The lower or annular table 12 is also provided with means for centering the blank and blow molds.

Such centering means being formed by disks 20, secured to the table in any suitable inanneras, for example, in the construction shown in Figs. 2 and 3the disks are formed with threaded stems 21, screwing into threaded openings in the table. As these disks form the bottoms of the blank andblow molds,

it is evident that their construction will vary in accordance with the article to be formed as, for example, in making lamps the disks are formed with central passages 22, the purpose of which will be hereinafter stated, and with recesses 23 in their upper side around said passages for the formation of the neck of the lamp or other article.

It will be readily understood that as the blank and blow molds have to be drawn out from between the tables after the blank and are made in sections; but in lieu of pivoting the sections together on the side opposite the handles, as is customary, they are pivoted and locked on the front .or handle side. To this .end one section of the mold is formed with a slotted stem 24, through which is passed the stem 25, secured to or formed on the other sect-ion of the mold. These stems are arranged in such relation to the sections that when the sections are closed the stem 25 will lie within the stem 24, as clearly shown in Figs. 2., 3, and 4. These stems are hinged together by a pin 26and are provided with holes outside of the pivot-pin for the reception of the locking-key 27, which is of the usual or any suitable form or construction.

While preferring to lock the mold-sections together by the key 27, the means shown in Figs. 3, 4, and 5 maybe employed. As shown, the mold-sections are provided on their rear or opening edges with fingers 28, which when the molds are in pressingor blowing positions are drawn together by the inclined edges of the clamping-plates 29. These plates are attached to the upper .ends of a rod 30, which projects up through the platform 7 and has its lower end connected to a lifting-treadle 31. The clamping-plate is drawn down to grip the fingers by spring32, surrounding the rod v3O. The clamping-plate is held in proper position by a second rod 30, but this function can be performed by any other suitable means.

As shown in Figs. 2 and 3, the blank-mold 33 and blow-mold 34 are formed with recesses in their upper and lower ends, so as to iuclose the .lowerends of the projections 16 on the press-molds and the disks 20 on the table 12, thereby holding all parts in true alinement during the pressing and blowing operations. The pressing mechanism consists of a shaping-plunger 35, which issecured in the usual manner to the rod 36.

in position is connected in the usual or any suitable manner to the rod 36. This rod is any other manner.

The spring presserplate 37 employed for holding the mold-ring connected to the cross head 38, movably mounted on the uprights 39, which are secured to the bed-plate 2. The cross-head is connected by pitmen 40 to arms 41 on the shaft 42, which is mounted in suitable bearings on the bed-plate. The shaft is rotated to shift the cross-head by a lever 43 or any other suitable means.

In order to form an initial opening in the bowl-blank, a pin 44 is passed up through the passage 22 in the disk 20 into the blank-mold. This pin is attached to a block 45, arranged in a guide 46, secured to an arm 47, attached to the central post or pillar l or supported in The block and pin are raised sufliciently to at least close the opening in the disk 20 by means of an angular treadle 48, the inner end of which strikes against lugs 42 on the block 45. The block and pin are supported in this initial position by a dog 50, so pivotally connected to the inner end of the treadle that when the latter is shifted to raise the block and pin the lower end of the dog will swing in and rest on the shaft 42.

After the pin 44 has been raised to initial position by the treadle glassis dropped intothe press-mold and the lever 43 is shifted to force down the shaping-plunger 35. By the rotation of the shaft 42 a cam .51 is moved under the block 45, thereby completely raising the pin 44 into the blank-mold or supporting the pin in the position to which it had been previously raised by the treadle 48. After the cam has passed under the block the dog is pushed off the shaft by a projection vF2 thereon, so that when the cam moves back from under theblock the latter will fall, withdrawing the pin from the mold and disk 20.

By the pressing operation such partsof .the article as the foot and neck are completely formed and the bowl portion .is givenIits initial shape. As soon as the shaping-plunger and pin are withdrawn the blank-mold is unlocked, opened, and drawn out onto the bracket 8, leaving the article suspended from the press-mold, but with its lower endor neck in engagement with the recess 23 in .thedisk20. The tables are now unlocked by shifting the locking-lever 53 out of engagement with .the notch in the table 12 and then rotated to bring the article to blowing position and to bring another press-mold topressin g position. The blow-mold is then pushed in andclosed around the bowl-blank, at the same time inclosing in the reccssesat its ends the disk 20 and the projection 16 on the press-m old, thereby insnring the proper centeringof .the blowmold. As soon as the blow-mold is closed and locked the lever 54 is lifted, thereby pressing the nozzle 55 of the movable blastpipe 56 against the under side of the table 12 with its opening in line with the passage 22 through the disk 20. The nozzle :is movable in the blast-pipe, so that when pressed against the table a .port will be opened automatieall y to permit the passage of air into the ICC IIO

-ble 6.

recess formed in the blank. Any form or construction of nozzle known in the art for this purpose may be employed. By the action of this air-blast the bowl-blank is expanded to conform with the blow-mold. After the bowl has been blown the blow-mold is unlocked,opened,and drawn out onto the bracket 9. By the time the bowl has been blown the pressing of another article has been completed and the blank-mold withdrawn, so that the tables can be unlocked and shifted. By this movement of the tables the completed article is brought to the bracket 10, where the press-mold is opened and the article removed through the slot in the edge of the ta- While the bracket 10 forms a convenient support on which the completed article can be placed, it may be omitted.

It is characteristic of my improvements that the parts of the article which are completed by the pressing operation are not moved with reference to their forming-surfaces during the movement of the tables or the carrying of the article from pressing to blowing position. It is also characteristic of my improvement that the blank from which the blown portion is to be formed is supported at its upper and lower ends while being shifted, thereby avoiding all liability of distortion.

As shown in Figs. 6 and 7, my improvements can be employed for manufacturing articles where it is necessary to force the air for expanding the body through the neck or portions formed by pressing, as in the manufacture of lnolassesjugs. In making such articles the disks 20 are replaced by the solid or imperforate disks 20, the upper surface of which is constructed to impart the desired contour to the bottom of the article. The press-molds 17 are similar to the molds 17, except as regards the contours of the glassshaping surfaces, which are constructed in accordance with rules well known in the art to produce the desired shapes. The blankmolds 33 and blow-molds 34: are altered only as regards their shaping-surfaces.

To efiect the top blow of the blank, a movable blast-pipe 56 is supported above the tables by arms 57, extending from the central post or pillar 1, as shown in Fig. 1. This blast-pipe, which is provided with a nozzle 55, having an automatically-operatin g valve, is moved to cause the nozzle to bear on top of the press-mold by means of a hand-lever 54. The lever and nozzle are supported in a raised position by a toothed bar 57, with which the lever engages, or by any other suitable means.

While the blank and blow molds have been described with some particularity, no claim is made herein for such construction of mold, as it forms the subject of anotherapplication, Serial No. 3,157, filed on or about January 29, 1900.

One of the essential characteristics of my improvement is the provision of suitable supports for the blank and blow molds under the positions occupied by the press-molds, such supports being movable with the pressmolds and maintained in alinement therewith, and hence as regards the broad terms of the claims the invention is not limited to the construction shown and described.

WVhile I have described the pressed portion of the article and the blank as being formed in two molds, the latter are practically two sect-ions of one mold, and the part described as the blow-mold is a section of said mold interchangeable with the blank-forming section.

It is characteristic of my improvements that the molds consist of three horizontal sections. One section is carried by the upper support and provided with a matrix suitable for shaping the pressed portion of the article. A second section is carried by the lower support and is constructed to shape a portion of the blank and a portion of the blown part of the article. The third section of the mold consists of two interchangeable parts, one adapted to form the blank and the other to form the blown part of the article.

I claim herein as my invention-- 1. In a machine for the manufacture of glassware the combination of a glass-pressin g and a glass-blowing mechanism, two movable supports for mold-sections arranged in different horizontal planes, each of said supports being provided with means for centering the mold-sections, means for adjusting said supports toward and from each other and means for securingthe equal and synchronous movements of both supports, substantially as set forth.
